months of TTC caused too much pain for me

We have been TTC for 16 months. For 16 months somebody we know announces they are preg. No one we knew was pregnant when we started TTC, no one had even voiced that they were TTC. For the last several months we have been getting pics of the newest deliveries. All the "we are expecting" and "we just had a ..." announcements have come as early as 4 days before my period started up to the day it started. We did have 2 mc and the wk before our first there was announcement (due in a month) and the wk after our second my nephew was born.

I decided to just let calls go the machine, not check email, MySpace, Facebook, anything that could end up breaking my heart the week before my period was due last month. Instead, I ran into a friend I hadn't seen in years and as soon as she turned around there was her 8 month baby bump. I just about broke down, it took everything I had to smile and congratulate her. I felt so hurt, there I was trying to avoid it only to have it shoved in my face. Then last wk we got the call she had the baby, another friend had a baby, and a friend that had a mc around our first mc was now 2 months. I told my husband I was done TTC. It's too hard having this thrust in my face month after month. No, my cycle is not over yet (will know on Saturday when it is due to start) but I am not getting hopes that high. I know that is very pessimistic but after 16 months of calling to the day the next announcement (and even the couple announcing) I am waving my white flag so I can try to move on and try to put all of this pain behind me or at least ease some of it. I believe God doesn't give us more than He knows we can handle but this time He gave me too much.
